All our Bluetooth audio amplifier boards which use CSR8635 (only U.FL interface version) Bluetooth chip can set a customized prompt tones. In this tutorial, We use TSA2210U as example to teach you how to change the prompt tones.
Hardware and Software required:
- TC2050-IDC-NL 10-Pin No-Legs Cable Kit
- CSR USB-SPI programmer
- Download CSRXX_ROM_ConfigTool_3.0.56 and install it
Step 1:
Convert audio file you want to set as tone to .wav format, encoding need to be PCM 16bit, Sampler 8kHz, Mono format.
Step 2:
Download CSRXX_ROM_ConfigTool_3.0.56 and install it. Connect CSR USB-SPI programmer and TC2050-IDC-NL 10-Pin No-Legs Cable Kit, then connect programmer to PC by a mini USB cable, Windows will auto detect it and install the drivers.
Step3:
Connect TC2050-IDC-NL’s connector to TSA2210U programming port, you need to locate the single steel alignment pin of the connector into the single hole of the PCB footprint, then press down softly to engage the spring-pin contacts. Make sure the first 6 pins have a good contact with the corresponding pads. Then the blue led and red led will flashes alternately.
Step4:
Open Config Tool and click "Open from Device", make sure platform is CSR8635 and continue.
